Expert Heat & Air Service Support From Cross Heat & Air
What is the average life expectancy of my heat & air service?
Most heat & air service systems have a lifetime of 10 to 20 years. As your equipment gets older, it’s efficiency can decrease dramatically. You may notice that it gets noisier and needs repairs more often. When a unit begins to show it’s age, you have two choices. You can overhaul the system or replace it. Because heating and cooling technologies improve over time, a new system designed with newer, more energy-efficient equipment makes sense, especially if your system is 10 or more years old. We can estimate the cost of a new system as well as a payback schedule that will show you how newer technology will pay you back in lower energy usage.
Can I just replace the outdoor unit on an older heat & air service system?
No. Replacing only the outdoor unit will lower the efficiency of your heat & air service. In fact, you can lose up to 15% of your heat & air service efficiency! Even worse, your system may fail sooner than normal and most manufacturers’ warranties will be voided. You should always replace the indoor cooling coil with the outdoor unit.
Will a larger heat & air service system perform better?
No, you don’t want your air conditioner to be too big, as this can lead to increased heat & air service costs. Air conditioners control the comfort level in your home by cooling the air and by removing humidity. An oversized air conditioner will cool your home faster, but it will use more energy and will not remove humidity adequately.
A unit that is too big for your home will have short run cycles. It may take only a short time to cool the air, but the unit shuts off before enough air blows across the indoor coil where moisture condenses into water and drains from your system. Too much moisture left in the air can lead to mold and mildew problems, leading to increased heat & air service issues.
These short run cycles also mean your system starts and stops more often which uses more energy and causes a lot of wear and tear. An air conditioner operates more efficiently during long run cycles.
The same holds true with heating systems. An oversized furnace will warm the house quicker, but it uses more fuel and causes greater temperature swings in the home.
Why is are matched components so important?
A matched heat & air service system is important for a variety of reasons. One is comfort. When all your components are properly sized to your home, you can control exactly how much heating or cooling you need so you can relax. Also, a properly sized matched system enables every component to perform as designed, meaning proper cycle times are maintained, humidity is controlled, and system sound is minimized.
Another reason matched systems are important is efficiency. Most systems people buy are too large for their homes, which uses more energy than needed for your home. A matched system outlined by a dealer who has completed a load calculation for your home provides just the right amount of heating and cooling you need so you get the most value for your utility dollar.
How often should I change my heat & air service filters?
At the risk of telling you something you’re tired of hearing, replace the air filter in your furnace on a regular basis. Dirty air filters reduce the amount of air flowing through a system and make the furnace work harder to maintain the temperature. How often you change the filter depends on the type of filter you use, if you have pets, and the size of your equipment. Please give us a call and we can give you proper guidance.
Should I switch to a high efficiency air filter?
Proper air filtration is just as important to the health of your heating and cooling system as it is to the health of your family. Without proper filtration, dust and dirt can build up on your system which impacts operation and efficiency. A high efficiency filter will remove more dust, dirt, pollen, mold, and other particles from the air. If you suffer from allergies or other respiratory problems, you should strongly consider a high efficiency filter. No matter what type of filter you have – make sure you change it regularly.
Should I have my system serviced every year?
Yes. Keeping your system properly maintained will lower energy and repair costs, prevent breakdowns, and prolong the life of your equipment. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases.
Why should I purchase a heat & air service agreement?
Without warranty coverage, a breakdown can mean significant expense in parts, labor, or both. However, with one of our heat & air service agreements, you avoid that unexpected significant expense. While no warranty can guard against every possible problem, we can explain the broad range of protection our service agreements afford.
What is duct cleaning?
Duct cleaning refers to the cleaning of the various heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, fan motor and fan housing, and the air handling unit housing.
What do SEER, AFUE, and HSPF ratings mean?
SEER, AFUE and HSPF are all measures of energy efficiency. Air conditioners may look similar, but their Seasonal Energy Efficiency Rating (SEER) can vary widely. Higher SEER numbers save more money spent on electricity. A 13 SEER air conditioner, the EPA “current minimum standard”, uses 23% less energy than a 10 SEER unit (EPA standard up until Jan. 2006). Even though 13 SEER is the minimum efficiency available, we currently offer a line of air conditioners that start at 13 SEER and go all the way up to a 21 SEER . Depending on your average usage, higher SEER air conditioners can significantly reduce your electric bill.
Heat pumps have SEER ratings like air conditioners and Heating Seasonal Performance Factor (HSPF) ratings for measuring heating efficiency. Higher HSPF ratings mean greater energy savings. The HSPF scale range is 7.5 to 13.0.
Today’s new high-efficiency furnaces can save up to 50% in operating costs over a ten-year-old furnace. Many 1990 and earlier model furnaces have Annual Fuel Utilization Efficiency (AFUE) ratings of 65% or less. The minimum AFUE rated furnace that can be sold in the United States as of May 1, 2013 is 80% in southern states and 90% in northern states.
Our current product offering starts at this minimum AFUE rating and goes all the way to a very efficient 98.3% AFUE rating. Depending on your average usage, higher AFUE rated furnaces can significantly reduce your gas bill.
How can I reduce my energy costs?
- Upgrade to a high-efficiency air conditioner – Swapping your old, inefficient air conditioning system for a high-efficient one can cut electricity bills by one-third. Consult one of our professional technicians to ensure your system is the right size for your home, and you aren’t over- or under-cooling for your space needs.
- Turn up the temperature – To save electricity during the summer, set the temperature above 75° as every degree below this will add an extra three to five percent to your energy bill.
- Install ceiling fans – Change the direction of airflow on your ceiling fans. In the summer, the blades should operate in a counter-clockwise direction as a way of creating a nice, gentle wind.
- Have an annual maintenance performed – Having an annual maintenance performed on your air conditioner by a licensed technician will help ensure it operates at its peak efficiency and catches any potential breakdowns before they occur.
- Don’t block vents in well-used rooms – Keep your supply and return air vents free of objects like blinds, carpets or furniture so your air conditioner can operate efficiently and there is even cool air distribution.
- Upgrade to a high-efficiency furnace – New high-efficiency furnaces use up to 50% less fuel than an older system. It can save you up to 25 per cent of your home-heating costs in one year, and within a few years, you’ll have recovered the initial cost of replacing/upgrading your furnace. Choosing a model with an energy efficient motor can save 20 to 50 percent of the energy needed to continuously operate a fan motor. Let us show you the advantages of replacing your old furnace today.
- Have an annual maintenance performed – Having an annual maintenance performed on your furnace by a licensed technician will help ensure it operates at its peak efficiency and catches any potential breakdowns before they occur.
- Install a programmable thermostat – A programmable thermostat enables you to control your home’s temperature when you’re away or asleep. For every 1° you lower your thermostat for seven hours per day, you save one percent on your heating bill.
- Don’t block vents in well-used rooms – Keep your supply and return air vents free of objects like blinds, carpets or furniture so your furnace can operate efficiently and there is even heat distribution.
- Install ceiling fans – Change the direction of airflow on your ceiling fans. In the winter, the blades should operate in a clockwise direction helping to push the warm air from the ceiling down into the room.
What is a Heat Pump?
Heat pumps are a great solution for your home comfort system because they work to provide both heating and cooling. Heat pumps have SEER ratings like air conditioners and Heating Seasonal Performance Factor (HSPF) ratings for measuring heating efficiency. Higher SEER and HSPF ratings mean greater energy savings.
Heat pumps are a very efficient alternative to electric heat. A heat pump works the same as an air conditioner in the summer, but it runs in reverse in the winter to heat your home. The system will be matched with a backup heating source, most often electric heat for those extremely cold days of winter.
What is a Geothermal System?
The Earth absorbs almost 50% of all solar energy and remains a constant temperature of 50°F to 70°F depending on geographical location. A geothermal unit utilizes this constant temperature for heating and cooling your home. You can realize up to 60% energy savings vs. traditional systems. There is no flame, no flue, no odors and no loud outdoor equipment. Heating, air conditioning and hot water can all be attained from a single compact unit.
What temperature should I set my thermostat?
Normal cooling settings are 75 degrees – 80 degrees. Normal heating settings are 68 degrees – 72 degrees. You should always set your thermostat to the highest possible setting that is comfortable for you in the summer, and the lowest comfortable setting in the winter. Setting your thermostat in this way will maximize your energy savings. On average, every 1 degree of temperature change is equal to about 1% energy savings. For example, changing your thermostat setting from 75 degrees to 76 degrees in the summer could result in savings on your cooling costs.
Is Freon being discontinued?
Yes. As of January 2010 the refrigerant R-22 (what consumers call Freon®) is no longer allowed to be used in the manufacturing of new equipment. R-22 has been used as the “standard” refrigerant for many years but has been found to be harmful to our planet by our government. All new air conditioners and heat pumps use R-410A, the more “environmentally sound” refrigerant.
R-22 is still the most commonly used refrigerant in existing air conditioning equipment in residential homes today. However, per the Montreal Protocol, caps have been established to eliminate the production of R-22. In 2004, there was a 35% reduction; in 2010 there was a 65% reduction; in 2015 a 90% reduction; and finally in 2020 a 99.5% reduction in the production of R-22. This means that during the time of these reductions with high demand, the price of each pound of R-22 refrigerant could potentially skyrocket.
If you are considering replacing your existing air conditioning equipment, most higher efficiency products have already made the switch to R-410A, the more “environmentally sound” refrigerant.
My air conditioner is very loud outside?
A difference of 6 decibels (such as between 72 dB and 78 dB) is technically a four-fold increase in compressor sound when rating heat & air service. However, it takes a difference of 10 decibels to double the loudness. It is also noted that it takes approximately 3 decibels for the average human ear to discern any difference in loudness at all.
Great strides have been made in reducing the operating sound level of equipment. We will be happy to show you the difference in sound ratings with our product line.
What if I smell gas?
Propane (LP) gas: You have this type if your gas comes from a tank located outside close to your house. Propane is stored as a liquid under pressure in tanks and cylinders to fuel your heat & air service. In most residential applications, propane is used as a vapor. When liquid propane changes into a gas vapor, it expands in volume. This means that even a small leak of liquid propane can result in a much larger quantity of propane vapor, which can be especially dangerous in a confined space. A chemical odorant has been added to propane to give it a distinct smell. Learn to identify this odor. Propane gas is heavier than air, so it will sink to the floor and spread. To check for the presence of propane, carefully smell all over a room, especially in low spots.
If you smell propane (LP) gas:
- Exit your home immediately.
- Propane gas can ignite easily. Do not light a match, start an engine, use a cell phone, or do anything that may create a spark.
- From a safe area, contact your propane supplier and call 911.
- If you are able, shut the propane gas supply off at the tank.
- Stay away from your home until you’ve been told that it is safe to return.
Natural gas: You have this type if you have a gas meter and pay a natural gas supplier or utility. A chemical odorant has been added to natural gas to give it a distinct smell. Learn to identify this odor to help your heat & air service.
If you smell natural gas:
- Exit your home immediately.
- Do not light a match, start an engine, use a cell phone, or do anything that may create a spark.
- From a safe area, contact your gas company or call 911.
- If you are able, turn the gas off at the meter.
- Stay away from your home until you’ve been told that it is safe to return.
